席丽  彭彦琴 《临沂师范学院学报》2007,29(6):136-139

近年来网上购物成为一种时尚,为满足不同层次的需要,消费者产生网上购物需求,这促使消费者去网上搜集产品信息,此时,注意、感知觉、情绪、记忆都会影响信息的搜集;接着人对林林总总的信息进行评价,当其感知风险低于可接受水平时,才会做出购买决策;然而又有很多心理因素影响决策甚至行为过程;最后消费者使用商品时会进一步评价该商品,这反过来会影响其新的购买需求的产生.  相似文献   

Social Constructivism and Asynchronous Text-Based Discussion: A Case Study with Trainee Teachers     

Kate Hawkey 《Education and Information Technologies》2003,8(2):165-177

The paper reports a case study using asynchronous text-based discussion. It considers the role of the tutor and discusses the extent to which online discussions can facilitate social constructivist approaches to instruction and the creation of knowledge. Participants were 17 trainee teachers studying on a post graduate teaching course. The asynchronous text-based discussion (using e-blackboard) focused on planning for progression in children's learning in history and culminated in the trainee teachers writing individual assignments on the topic. The paper analyses the different types of contributions made and reports on the trainees' evaluations of the benefits and limitations of using e-blackboard. It concludes with recommendations and areas for further research.  相似文献   

在线课程质量观和质量要素的质性研究--基于专家、实践者和学习者的视角     

李爽  李梦蕾  赵宏 《中国远程教育(综合版)》2020,(3):42-50,81

本文采用扎根理论研究方法,通过对学术专家、实践者和学习者三类相关群体的访谈,调查高等教育和继续教育在线课程相关人群关于在线课程的质量观与对质量构成的认识,探索在线课程质量框架与要素,以期为促进人们对在线课程质量的共识,为改进和优化现有在线课程质量标准提供参考。研究通过对20位受访者累计22万字访谈文本的编码分析,发现四种质量观--服务质量观、系统性质量观、目标性质量观和增值性质量观,并定义出设计开发与实施运行两大类的九个在线课程质量要素--课程目标、课程内容、学习过程、学习支持服务、学习评价、媒体与技术环境、实施效果、改进发展和社会影响。其中,课程目标、学习内容与实施效果被定义为核心要素。本文基于TF-IDF关键词统计方法对三类群体的在线课程质量观差异进行了分析,并结合已有远程教育质量观和在线课程质量标准相关成果对本研究发现和定义的在线课程质量观、质量框架和质量要素进行了讨论与反思。  相似文献

婚姻法中新增设的探望权制度,有其积极作用,但在保护子女利益方面还需完善,本文提出在坚持以保护子女利益为核心的立法宗旨的基础上,应赋予子女探望权的主体资格,子女对探望权的行使具有选择权,在一定情况下,子女有权拒绝父母的探望,而父母却不能自动抛弃其探望权。  相似文献

Enhancing the facilitation of online groups in higher education: a review of the literature on face-to-face and online group-facilitation     

Glyn Thomas  Stephen Thorpe 《Interactive Learning Environments》2019,27(1):62-71

There still appears to be a gap between what online learning promises and what it can deliver in terms of student learning. Developments in online pedagogies and professional learning appear to lag behind the developments in technology and the promised benefits of technological transformation may not be realised. In this paper, we bring together perspectives that highlight vital aspects of online group-learning by reviewing the group-facilitation literature and the latest online learning literature to interrogate the pedagogical theories and practices currently used in online group-learning in higher education. We specifically focus on the interpersonal interactions between teachers and students, which are described in the online learning literature using the terms instructor immediacy, teaching presence, and social presence. We note differences in the literature regarding how teacher presence is interpreted and enacted and we expound the importance of the personal characteristics of the online teacher. Finally, we provide some signposts that might help course designers and teachers to improve online group learning: the intentional use of effective online learning pedagogies; a deeper understanding of what constitutes teacher presence; and strategies to enact that teacher presence with online groups. Recommendations for further research in online group facilitation are provided.  相似文献

New Media/Internet Research Topics of the Association of Internet Researchers     

Ronald E. Rice 《The Information Society》2005,21(4):285-299

This study summarizes prior reviews of new media and Internet research, and the growth of the term Internet in academic publications and online newsgroups. It then uses semantic network analysis to summarize the interests and concepts of an interdisciplinary group of Internet researchers, as represented by session titles and paper titles and abstracts from the 2003 and 2004 Association of Internet Researchers conferences. In both years, the most frequent words appearing in the paper abstracts included Internet, online, community, social, technology, and research. The 2003 papers emphasized topics such as the social analysis/research of online/Internet communication, community, and information, with particular coverage of access, individuals, groups, digital media, culture; role and process in e-organizations; and world development. The 2004 papers emphasized topics such as access; news and social issues; the role of individuals in communities; user-based studies; usage data; and blogs, women, and search policy, among others.  相似文献
